Mid-infrared spectroscopy is a type of spectroscopy that focuses on the study of the mid-infrared region of the electromagnetic spectrum, typically ranging from around 2.5 to 25 micrometers in wavelength. This technique is commonly used in chemistry and materials science to analyze molecular vibrations in compounds, as different functional groups exhibit characteristic absorption bands in this region. Mid-infrared spectroscopy is particularly useful for identifying and characterizing organic compounds, polymers, and minerals. It is a non-destructive and rapid analytical technique that can provide valuable information about the structure, composition, and bonding of a wide range of materials.
